TC-400-TM-X TNC Male Straight Solder Connector for LMR-400 Coaxial Cable
TC-400-TM-X Connector is a precision-engineered TNC Male (plug) connector specifically designed for the reliable termination of LMR-400 and other 400-series flexible low-loss coaxial cable. Featuring the traditional solder-pin center contact, this connector provides a durable, low-resistance connection essential for high-power or demanding RF environments. Its threaded TNC coupling ensures secure mating and excellent electrical performance up to 6 GHz.
Key Features & Advantages
- LMR-400 Optimized: Precision matched to the dimensions and electrical characteristics of LMR-400 coaxial cable, ensuring maximum performance and minimum reflection (VSWR < 1.30:1 up to 6 GHz).
- Solder-Pin Center Contact: Provides a strong, permanent, low-resistance electrical connection to the center conductor, making it an excellent choice for stranded center conductors where solderless designs may be less suitable.
- TNC Threaded Interface: Features the robust, miniature threaded coupling mechanism, offering high mechanical stability and superior performance compared to the BNC series, especially in high-vibration or outdoor environments.
- High Frequency Performance: Supports reliable signal transmission up to 6 GHz, meeting the demands of modern wireless and telecommunications applications.
- Durable Tri-Metal Plating: Constructed from brass with an Alballoy (White Bronze) body finish and Gold-plated center pin for excellent corrosion resistance and longevity.
